I think the new rule would be much more palatable if it was 100X the TERRAFORMED resources of the star rather than the NATURAL resources.
The former is much more scalable as “inflation” naturally increases the number of ships … with a corresponding increase in Terra. Plus I’ve actually played a couple of games where it was setup starting with TF10 - adds an interesting dimension to the game … but you could hit that production limit pretty soon.
BTW, even if you put a message up on the “star screen”, players may not notice that production has stalled since the ship counts are kinda high.
@cptcrackers makes some good points in that this may balance the scales even more in favor of the player with more stars - if anything, you want to give the weaker players some way to fight back.
